RexIDE - https://rex.mindmeld360.com In this episode, we design a local, ultra-fast delivery system inspired by GoPuff. We break down: service boundaries (ordering, inventory, dispatch) real-time courier assignment warehouse-centric delivery vs marketplace models latency, batching, and failure scenarios

RexIDE - https://rex.mindmeld360.com We explore the fundamental concept of Happens-Before (HB)—not a measure of time, but a formal mathematical relationship that provides the only real guarantee of visibility and ordering in a multi-threaded world. Without an HB edge, your threads are effectively living in different realities, where one thread might see an object has been published but observe its internal fields as stale or uninitialized zeros.
